swift - 在ios swift4中通过纬度和经度创建 map 图像

Question

通过 API，我有特定位置的纬度和经度，需要在 ImageView 上以 map 形式显示这些坐标。我想通过这些坐标绘制 map View 图像。想要显示特定位置以及经纬度。我怎样才能做到？

Answer 1

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    if locationUpdate == false {
        locationUpdate = true
        guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
        print("locations = \(locValue.latitude) \(locValue.longitude)")
        var latStr = ""
        var longStr = ""
        latStr = String(locValue.latitude)
        longStr = String(locValue.longitude)

        let staticMapUrl = "http://maps.google.com/maps/api/staticmap?markers=color:blue|\(latStr),\(longStr)&\("zoom=10&size=400x300")&sensor=true&key=AIzaSyBXAdCe4nJuapECudMeh4q-gGlU-yAMQX0"

        print(staticMapUrl)

        let url = URL(string: staticMapUrl.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!)

        do {
            let data = try NSData(contentsOf: url!, options: NSData.ReadingOptions())
            imgLocationOnMap.image = UIImage(data: data as Data)
        } catch {
            imgLocationOnMap.image = UIImage()
        }


    }
}
